Nectarine tree named &#39;burnectthirtytwo&#39;

ABSTRACT

A new and distinct variety of nectarine tree ( Prunus persica nucipersica ), which is denominated varietally as ‘Burnectthirtytwo’, and which produces an attractively colored yellow fleshed, clingstone nectarines which is mature for harvesting and shipment approximately July 12 to July 19 under the ecological conditions prevailing in the San Joaquin Valley of central California.

Botanical designation: Prunus persica nucipersica.

Varietal denomination: Burnectthirtytwo.

BACKGROUND OF THE NEW VARIETY

The present variety of nectarine tree resulted from an on-going programof fruit and nut tree breeding. The purpose of this program is toimprove the commercial quality of deciduous fruit and nut varieties, androotstocks, by creating and releasing promising selections of Prunus,Malus, Punica and Juglans species. To this end we make both controlledand hybrid cross pollinations each year in order to produce seedlingpopulations from which improved progenies are evaluated and selected.

The seedling, ‘Burnectthirtytwo’ was originated by us, and selected froma population of seedlings growing in our experimental orchards which arelocated near Fowler, Calif. The seedlings, grown on their own roots,were derived from planting seed secured from an open-pollinatedseedling, ‘J10.064’ which is non-patented, and which further produces awhite-fleshed, clingstone nectarine. The resulting fruit was collectedfrom the open-pollinated seedling at a mature stage, and the seeds wereextracted in June of 2005. After a period of stratification, the seedwas placed in the greenhouse by population, and then field planted fortree establishment, and ultimately to exhibit fruit for furtherevaluation. One seedling which produced a yellow fleshed nectarine,which is the present variety, exhibited especially desirablecharacteristics, and was then designated as ‘N53.082’. This new seedlingwas marked for subsequent observation. After the 2008 fruiting season,the new variety of nectarine tree was selected for advanced evaluationand repropagation.

ASEXUAL REPRODUCTION

Asexual reproduction of this new and distinct variety of nectarine treewas accomplished by budding the newly discovered nectarine tree onto 30trees established on ‘Nemaguard’ Rootstock (un-patented). This wasperformed by us in our experimental orchard which is located nearFowler, Calif. Subsequent evaluations of these asexually reproducedtrees have shown those asexual reproductions run true to the originaltree. All characteristics of the original tree, and its fruit, wereestablished, and appear to be transmitted through these succeedingasexual propagations.

SUMMARY OF VARIETY

‘Burnectthirtytwo’ is a new, and distinct variety of nectarine tree,which is considered of relatively large size, and which has a vigorousgrowth characteristic. This new tree is also a regular and productivebearer of relatively large, firm, yellow-fleshed, acidic, clingstonefruit which have a very good flavor, and eating qualities. This newnectarine tree has a medium chilling requirement of approximately 650hours, and further produces relatively uniformly sized fruit throughoutthe tree's canopy. In addition to the foregoing, the fruit of the newnectarine also appears to have good handling and shipping qualities. The‘Burnectthirtytwo’ Nectarine tree bears fruit which are typically ripefor commercial harvesting and shipment on approximately July 12 to July19 under the ecological conditions typically prevailing in the SanJoaquin Valley of central California. In relative comparison to the‘Summer Bright’ nectarine tree (U.S. Pat. No. 7,049), and which is theclosest known variety, the current variety of nectarine tree bears aclingstone fruit that is generally 5.0 millimeters larger. Further, thecurrent variety produces fruit which exhibits a more oblate, and lesselongated shape than the fruit produced by the ‘Summer Bright’ nectarinetree. In relative comparison to the unpatented ‘J10.064’ nectarine tree,the new variety is clearly distinguished by producing fruit having ayellow flesh, whereas the seed parent ‘J10,064’ produces fruit having awhite flesh characteristic.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new anddistinct variety of nectarine tree, the following has been observedduring the tenth fruiting season, and under the ecological conditionsprevailing at the orchards of the assignee which are located near thetown of Fowler, county of Fresno, state of Calif. All major color codedesignations are by reference to the R.H.S. Colour Chart (RoyalHorticultural Society, Fourth Edition, 2001) provided by The RoyalHorticultural Society of Great Britain. Common color names are alsooccasionally used.

-   Tree:    -   -   Size.—Generally considered medium to medium-large in its            growth pattern as compared to other common commercial            nectarine cultivars ripening in the late season of maturity.            The tree of the present variety was pruned to a height of            approximately 270.0 cm. to about 310.0 cm. at commercial            maturity.        -   Width.—Approximately 265.0 cm.        -   Vigor.—Considered moderately vigorous. The present peach            tree variety grew from about 175.0 cm. to about 180.0 cm.,            in height, during the first growing season. The new variety            was then pruned to a height of approximately 150.0 cm.            during the first dormant season, and primary scaffolds were            then selected for the desired tree structure.        -   Productivity.—Productive. Fruit set varies from more than            the desired crop load, to levels higher than desired            amounts, when the new variety is grown in a suitable            horticultural zone, and under appropriate commercial nursery            conditions. The fruit set is spaced by thinning to develop            the remaining fruit into the desired market-sized fruit. The            number of the fruit set varies with the prevailing climatic            conditions, and the cultural practices employed.        -   Fruit bearing.—Regular. Fruit set has been more than            adequate during the previous years of observation, and            thinning was necessary during the past 10 years on both the            original seedling, and on subsequent asexually reproduced            trees.        -   Tree form.—Upright, and pruned into a vase shape.        -   Tree density.—Considered moderately dense. It has been            discovered that pruning the branches from the center of the            new tree to obtain a resulting vase shape allows for            enhanced air movement, and appropriate amounts of sunlight            to enter the tree canopy so as to improve the resulting            fruit color, and a renewal of fruiting wood throughout the            tree canopy.        -   Hardiness.—The present tree was grown and subsequently            evaluated in USDA Hardiness Zone 9. The calculated winter            chilling requirements of the new tree is approximately 500            hours at a temperature below 7.0 degrees C. The present            variety appears to be hardy under typical central San            Joaquin Valley climatic conditions.-   Trunk:    -   -   Diameter.—Approximately 17.5 cm in diameter when measured at            a distance of approximately 15.24 cm. above the soil level.            This measurement was taken from one of the new trees at the            end of the 7th growing season.        -   Bark texture.—Considered moderately rough, and displaying            folds of papery scarfskin. Since bark development and            coloration change with advancing tree age this            characteristic varies with the tree vigor, tree age and the            regional environmental conditions under which the tree was            grown. Therefore, this is not a dependable descriptor for            the new variety.        -   Lenticels.—Numerous flat, and oval lenticels are present.            The lenticels range in size from approximately 5.0            millimeters to about 7.0 mm. in width; and between about 1.0            and about 2.0 millimeters in height. The development and            size of the trunk lenticels can be influenced, to some            degree, by the ambient growing conditions experienced by the            tree, and are not, necessarily, a dependable characteristic            for this variety. As trees of this new variety mature,            lenticels are present, but they are typically covered, over            time, by increasing layers of cork (mature bark), and            therefore become less apparent to an observer.        -   Lenticel color.—Considered an orange brown, (RHS            Greyed-Orange Group 164 B).        -   Bark coloration.—Variable, but it is generally considered to            be a greyed brown, (RHS Grey-Green Group 197 B). This bark            description was taken from trees that were six years old and            which have further ruptured the scarf skin, and which            further also have developed bark furrowing that is much more            typical of the bark of older trees. It should also be noted            that the coloration of the bark is influenced, and varies,            as the smoother, darker background color of the bark            approaches other bark features such as the lenticels, and            the initial fissures form a feature of the scarf skin            development.-   Branches:    -   -   Size.—Considered medium large for the variety.        -   Branch diameter.—Average as compared to other nectarine            varieties. The branches have an average diameter of about            11.0 centimeters when measured during the 6th year after            grafting.        -   Flowering shoot thickness.—Average for the species.            Generally, the most consistent flower bud development, and            therefore potential fruiting sites occur on shoots which are            approximately 5.0 millimeters in diameter, or larger, but            generally less than 13.0 millimeters in diameter, at the            time of bloom.        -   Surface texture.—Average, and appearing relatively smooth            but with more furrowing being observed on wood which is            several years old.        -   Crotch angles.—Primary branches are considered variable, and            are usually growing at an angle of about 42 to about 50            degrees when measured from a horizontal plane. This            particular characteristic can vary due to the influence of            the variable ecological conditions, and cultural practices            which are employed.        -   Current season shoots.—Surface texture — Substantially            glabrous.        -   Internode length.—Approximately 2.4 cm.        -   Color of mature branches.—Generally speaking a grey-brown,            (RHS Greyed-Orange Group 177 C).        -   Current season's shoots.—Color. — Light green, (RHS            Yellow-Green Group 145 C). The color of the new shoot tips            is considered a bright and shiny green (RHS Yellow-Green            Group 146 D). The vegetative shoot color can be            significantly influenced by plant nutrition, irrigation            practices, and exposure to sunlight, and therefore should            not be considered a consistent botanical characteristic of            this new variety of tree.-   Leaves:    -   -   Size.—Considered somewhat elongated and narrow for the            species. Leaf measurements have been taken from vigorous,            upright, current-season growth, taken at approximately            mid-shoot. It should be understood that the leaf size is            often influenced by the prevailing growing conditions,            quality of sunlight, and the location of the leaf within the            tree canopy. For this reason, leaf sizes can vary somewhat            significantly based upon the ambient and other cultural            factors listed above, and are not typically considered a            dependable botanical descriptor.        -   Leaf length.—Approximately 148.0 to about 155.0 millimeters.        -   Leaf width.—Approximately 30.0 to about 33.0 millimeters.        -   Leaf base-shape.—The leaves generally exhibit substantially            equal marginal symmetry relative to the leaf longitudinal            axis.        -   Leaf form.—Lanceolate.        -   Leaf tip form.—Acuminate.        -   Leaf color.—Upper Leaf Surface — Medium green,            (approximately RHS Green Group 137 A).        -   Leaf texture.—        -   Upper and lower leaf surfaces.—Glabrous. Leaf Color. — Lower            Leaf Surface — Medium green, (approximately RHS Green Group            146 B).        -   Leaf venation.—Pinnately veined.        -   Mid-vein.—Color — Considered a light yellow, (approximately            RHS Greyed-Yellow Group 160 C) in the early to mid-period of            the growing season.        -   Leaf margins.—Gently undulating.        -   Marginal form.—Considered finely crenate.        -   Marginal uniformity.—Generally uniform.        -   Leaf petioles.—        -   Form.—Considered canaliculated, and having a more pronounced            trough when viewed from the dorsal aspect. The petiole            margin is considered rounded when viewed from the ventral            aspect.        -   Size.—Considered medium-small for the species.        -   Length.—About 8.0 to about 11.0 mm.        -   Diameter.—About 1.5 to about 2.0 mm.        -   Leaf petiole color.—Light yellow green, (approximately RHS            Yellow-Green Group 145 A).        -   Texture.—Glabrous.        -   Strength.—Generally considered durable for the species until            senescence is reached.        -   Leaf glands.—        -   Size.—Considered relatively small for the species;            approximately 2.0 mm. in length; and about 1.0 mm. in            height.        -   Number.—Generally one, and less commonly two glands appear            along each marginal side. Observations of more than two            glands per marginal side are very uncommon.        -   Type.—Leaf glands located at the base of the leaf are            predominantly reniform in shape. An additional one to two,            or occasionally more leaf glands, which appear reniform, and            stalked, are often present at the basal margin of the leaf            petiole as well.        -   Color.—Considered a medium-dark brown, approximately (RHS            Brown Group 199 A). Typically the coloration of the glands            darkens, and occasionally begins to desiccate during the            mid-late growing season.        -   Leaf stipules.—        -   Size.—Medium large for this variety.        -   Numbers.—Typically 2 per leaf bud, and up to 6 per shoot tip            are seen.        -   Form.—Lanceolate in form, and having a serrated marginal            edge.        -   Color.—Green, (approximately RHS Green Group 137 B) when            young, but graduating to a brown color, (approximately RHS            Greyed-Orange Group 165 A) with advancing senescence. The            leaf stipules are generally considered to be early            deciduous.-   Flower buds:    -   -   Hardiness.—No winter injury (bud death) has been seen during            the last several years of observation in the central San            Joaquin Valley. The new variety of nectarine tree has not            been intentionally subjected to drought, cold or heat            stress, and therefore this information is not available.        -   Flower bud.—Size — Variable, and dependent upon the state of            maturity. The flower buds as described were observed            approximately 7 days prior to bloom, about Feb. 13, 2016.        -   Length.—Approximately 15.5 millimeters.        -   Diameter.—Approximately 8.5 millimeters.        -   Surface texture.—Pubescent.        -   Orientation.—Considered appressed, but appearing less so as            the blossoms near opening.        -   Bud scale color.—Approximately RHS Greyed-Orange Group 175            A.-   Flowers:    -   -   Date of first bloom.—Observed on Feb. 20, 2016.        -   Blooming time.—Considered average in relative comparison to            other commercial nectarine cultivars grown in the central            San Joaquin Valley. The date of full bloom was observed on            Feb. 28, 2016. The date of full bloom varies slightly with            climatic conditions, and the prevailing cultural practices            which are employed.        -   Duration of bloom.—Approximately 8 or more days. This            particular characteristic varies slightly with the            prevailing climatic conditions.        -   Flower class.—Considered a perfect flower, complete and            perigynous.        -   Flower type.—The variety is considered to have a showy-type            flower.        -   Flower size.—Considered large. The flower diameter at full            bloom is approximately 57.0 to 60.0 millimeters.        -   Bloom quantity.—Considered abundant.        -   Flower bud density.—Generally considered dense.        -   Flower bud frequency.—Generally two flower buds appear per            node, and occasionally one flower bud per node is observed.            On very rare occasions three floral Bud's per node are            observed.        -   Petal size.—Generally considered large for the species.        -   Petal length.—Approximately 26.0 to 28.0 millimeters.        -   Petal width.—Approximately 21.0 to 26.0 millimeters.        -   Petal form.—Considered broadly ovate.        -   Petal count.—Nearly always 5.        -   Petal texture.—Upper and Lower Petal Textures. — Very finely            pubescent, and satin like.        -   Petal color.—Considered a light pink at the popcorn stage,            (RHS Red-Purple Group 65 B); and darkening with advanced            senescence, and the exposure of sunlight, to a medium-dark            pink, (RHS Red-Purple 63 C). This darkening of the petal            color is generally most noticeable within the margins of the            petal claw.        -   Fragrance.—Slight.        -   Petal claw.—        -   Form.—The claw is considered ovate, and is generally large            in size.        -   Length.—Approximately 14.0 to 16.0 millimeters.        -   Width.—Approximately 10.5 to 14.0 millimeters.        -   Petal margins.—Generally speaking, they are moderately            undulate and ruffled, especially apically.        -   Petal apex.—Generally — The petal margin often exhibits a            shallow, and wide recess at the tip.        -   Width.—Approximately 2.5 to 4.0 millimeters.        -   Depth.—1.0 to 2.0 millimeters.        -   Flower pedicel.—        -   Length.—Considered medium-long with an approximate length of            about 1.5 to about 3.5 millimeters.        -   Diameter.—Approximately 2.5 millimeters.        -   Flower pedicel color.—A medium brown, approximately (RHS            Grey-Brown Group N199 D) depending upon the pedicel, and            fruit maturity, and the timing of the visual observation.        -   Strength.—Tenacious. This is considered average for the            species.        -   Texture.—Generally smooth, to slightly undulate.        -   Floral nectaries.—Color. — Considered a dull brown            (approximately RHS Greyed-Orange Group 175 B).        -   Calyx.—        -   Surface texture.—Generally glabrous.        -   Color.—A dull grey purple, (approximately RHS Greyed-Purple            Group 185 B).        -   Sepals.—        -   Upper surface texture.—Moderately pubescent.        -   Lower surface texture.—Finely pubescent.        -   Number.—5 sepals are usually observed.        -   Size.—Generally medium large.        -   Sepal length.—Approximately 5.0 to 8.0 millimeters.        -   Sepal width.—Approximately 4.0 to 6.0 millimeters.        -   Sepal shape.—Generally obovate.        -   Sepal margin.—Considered smooth, and entire.        -   Sepal color.—A dull grey purple, (approximately RHS            Greyed-Green Group 197 B).        -   Anthers.—        -   Size.—Average.        -   Color.—Yellow when viewed dorsally, and prior to dehiscence,            (approximately RHS Greyed-Yellow Group 162 B).        -   Position relative to the stigma.—Generally the stigma is            superior to the anthers by approx. 1.0-2.0 millimeters.        -   Pollen production.—Pollen is abundant, and has a yellow            color, (approximately RHS Yellow-Orange Group 18 A).        -   Fertility.—Self-fertile.        -   Filaments.—        -   Size.—Approximately 17.5 to 20.0 millimeters in length.        -   Color.—Generally considered white, (RHS Red Yellow Group 11            D).        -   Pistil.—        -   Number.—Usually one, and only rarely more than one is            observed.        -   Size.—Generally considered large.        -   Length.—Approximately 19.0 to about 22.0 millimeters,            including the ovary.        -   Color.—Considered a very pale green, (approximately RHS            Yellow-Green Group 154 D).        -   Surface texture.—The variety has a long glabrous pistil.        -   Position relative to the petals.—At flower maturity the            stamens grow to be superior to the petals.-   Fruit:    -   -   Maturity when described.—Firm ripe condition (shipping            ripe).        -   Date of first picking.—Approximately Jul. 8, 2016.        -   Date of last picking.—Jul. 14, 2016. The date of harvest can            vary with the prevailing climatic conditions, crop loads and            the cultural practices which are employed.        -   Size.—Generally — Considered medium-large.        -   Average cheek diameter.—Approximately 76.0 to about 80.0            millimeters.        -   Average axial diameter.—Approximately 74.0 to about 79.0            millimeters.        -   Typical weight.—Approximately 225.0 grams. This            characteristic is quite dependent upon the prevailing            cultural practices, and ambient growing conditions.            Consequently this characteristic is not particularly            distinctive of the new variety.        -   Fruit form.—Generally — Considered globose. The fruit is            generally very uniform in its symmetry.        -   Mucron tip.—Absent.        -   Fruit suture.—No stitching exists along the suture line.        -   Suture.—Color — Generally, the fruit suture appears blushed            to the same degree as the skin, (approximately RHS            Orange-Red Group 34 A).        -   Ventral surface.—Form — Considered even, and uniform in            appearance, when it is viewed from the lateral, sutural            plane.        -   Apex.—Shape — Rounded to slightly rutuse.        -   Base.—Shape — Generally smooth.        -   Stem cavity.—Generally — The stem cavity has a rounded            circular form or shape which is usually considered uniform.            The rounded stem cavity slightly extends toward the suture.            The average depth of the stem cavity is about 8.0-10.0 mm.            The average width of the stem cavity is about 26.0 mm. The            average length of the stem cavity, when measured in the            suturial plane, is about 45.0 mm.        -   Fruit skin.—        -   Thickness.—Considered medium in thickness, and tenacious to            the flesh.        -   Surface texture.—Glabrous.        -   Taste.—Non-astringent.        -   Tendency to crack.—Not observed in the previous years of            observation and evaluation.        -   Fruit skin color.—        -   Blush color.—Generally speaking, a red blush exists on a            majority of the skin of the fruit (approximately RHS            Orange-Red Group 34 A), and is more typically present on the            portions of the fruit facing the sunlight. The blush of the            fruit typically covers approximately 75%-95% of the fruit            skin surface. The percentage of the blush on the fruit skin            surface can vary, and is generally dependent upon the            fruit's exposure to direct sunlight; specific fruit            maturity; and also the prevailing ecological and cultural            conditions under which the fruit was grown.        -   Ground color.—A medium, light orange yellow, (approximately            RHS. Yellow-Orange Group 23 C). The ground color of the            fruit can vary significantly based upon the maturity of the            fruit when this measurement is taken, and generally acquires            a lighter, and less green cast with increasing maturity.        -   Fruit glossiness.—The fruit is considered to be glossy.        -   Fruit stem.—        -   Size.—Medium in length, approximately 6.0 to about 8.0            millimeters.        -   Diameter.—Approximately 2.0 to about 3.0 millimeters.        -   Color.—Pale yellow-green, (approximately RHS Yellow-Green            Group N144 C).        -   Fruit flesh.—        -   Ripening.—Considered even.        -   Texture.—Considered firm, crunchy, juicy and dense.        -   Fibers.—Present, but not prominent.        -   Aroma.—Slight.        -   Eating quality.—Considered very good.        -   Flavor.—Considered balanced with both sweetness, and            acidity.        -   Juice production.—Moderate.        -   Brix.—About 11.0 to 13.5 degrees. This particular            characteristic varies slightly with the number of fruit per            tree; the maturity of the fruit when harvested; the            prevailing cultural practices employed in growing the new            tree; and the ambient climatic conditions.        -   Acidity.—Considered low. Approximately 0.8 titratable            acidity is typically detected. The acid levels assayed from            fruit flesh can vary based upon the fruit maturity, sunlight            exposure, and the climatic, regional and cultural influences            the tree was exposed to.        -   Flesh color.—It is considered yellow, (approximately RHS            Yellow-Orange Group 17 D). A slight pigmentation of pink red            can be seen radiating from the stone (approximately RHS Red            Group 39 A).-   Stone:    -   -   Stone type.—Considered a clingstone.        -   Stone size.—It is generally considered to be medium for the            species. The stone size varies significantly depending upon            thd tree vigor, the crop load, and the prevailing growing            and cultural conditions under which the tree was grown.        -   Stone length.—Average, about 30.0 to about 35.0 millimeters.        -   Stone width.—Average, about 23.0 to about 27.0 millimeters.        -   Stone diameter.—Average, about 17.0 to about 20.0            millimeters.        -   Stone form.—Roughly ovoid.        -   Stone base.—Shape — The stone is considered shortly            attenuate.        -   Stone apex.—Shape — The stone exhibits a slightly acute            apex.        -   Stone surface texture —Considered irregularly furrowed            toward the apex. Further, more pitting exists in the            mid-portion of the stone (laterally), and is more commonly            observed toward the base.        -   Stone ridges.—Ridging is generally more prominent, and is            usually oriented parallel, and laterally relative at the            ventral and dorsal margins.        -   Stone ventral edge.—The ventral edge has adjoining ridges            formed from each hemisphere. There are longitudinal grooves            running alongside this joined, ventral suture. Secondarily,            there can exist an additional set of parallel ridges, one on            each side of the major ridge. These secondary ridges are            less prominent, and do not always extend from the hilum to            the apex.        -   Dorsal edge.—Shape — Generally considered even. The folds of            the surface ridges appearing on the external margins often            end gently along the suture.        -   Stone color.—The color of a mature, dry stone is generally            considered a dull brown, approximately (RHS Greyed-Orange            Group 165 D). The stone color can vary considerably based            upon how recently the fruit has ripened; the degree of            oxidation it has experienced; and any blanching which has            taken place by way of exposure of the stone to sunlight.        -   Tendency to split.—Splitting has rarely been noted.        -   Kernel.—        -   Length.—Approximately 16.0-19.0 millimeters.        -   Width.—Approximately 12.0-15.0 millimeters.        -   Thickness.—4.0-6.0 millimeters.        -   Size.—The kernel is considered medium in size.        -   Form.—Considered generally ovoid.        -   Kernel surface texture.—The kernel pellicle is shortly            pubescent.        -   Color.—A dark tan (RHS Greyed-Orange Group 165 C).        -   Use.—The present variety ‘Burnectthirtytwo’ is considered to            be a nectarine tree of the late season of maturity, and            which produces fruit which are considered to be firm,            attractively colored, and which further are useful for both            local and long distance shipping.        -   Keeping quality.—Appears excellent. The fruit of the present            variety has stored well for periods of up to 35 days after            harvest at 1.0 degree Celsius.        -   Shipping quality.—Good. The fruit of the new nectarine tree            variety showed minimal bruising of the flesh or skin damage            after being subjected to normal harvesting and packing            procedures.        -   Resistance to insects and disease.—No particular            susceptibilities were noted. The present variety of            nectarine tree has not been intentionally tested to expose            or detect any susceptibilities or resistances to any known            plant, fruit diseases, insect, frost, winter injury or other            environmental factors. Although the new variety of nectarine            tree possesses the described characteristics when grown            under the ecological conditions prevailing near Fowler,            Calif., in the Central part of the San Joaquin Valley of            California, it should be understood that variations of the            usual magnitude, and characteristics incident to changes in            growing conditions, fertilization, nutrition, pruning, pest            control, frost, climatic variables and changes in            horticultural management practices are to be expected.

Having thus described and illustrated our new variety of nectarine tree,what we claim is new, and desire to secure by plant Letters Patent is:1. A new distinct variety of nectarine tree, substantially asillustrated and described, and which is characterized principally as tonovelty by producing an attractively colored yellow fleshed, clingstonenectarine which is mature for harvesting and shipment approximately July12 to July 19 under the ecological conditions prevailing in the SanJoaquin Valley of central California.
